Single Channel (Low Cost) Gateway
kersing: If you read the LoRaWAN spec chapter 7.1.2 (page 34) it states a gateway should always listen on three default channels with data rates DR0 to DR5. So a single channel gateway can never...

With the 72 uplink channels we have in the USA, and the limitation of current gateways to 8 channels, we have some frequency planning to do. The 72 uplink channels are divided into 8 sub-bands, each...

Interesting simulation. How can this be translated to real life production situations?I should think that lost packages can not be monitored from the gateway...But is there a measure on the gateway...

I have used Dweet.io as an external server to push the data from my device.Freeboard.io will then use Dweet.io as the datasource for plots/graphs.

Universal LoRa(WAN) gateway limitations, because physics?
If we take a look at this picture (thanks to Maarten Weyn) we see the random selection of spread factor seems to be the main issue here. i.e. more SF12 due to longer transmission times....
View ArticleUniversal LoRa(WAN) gateway limitations, because physics?
About my question... I already know part of the answer...If gateway area is overlapping the SF12 regions will be minimized and every node will be in the higher spreadfactors. This solves our problem...

Downstream data packet
@scle You're completely right. I tried to put the data string in a buffer with 'base64' while 'ascii' should be used. Currently I'm getting this "data":"YPh6GwAgAgCzj+N3" <-My...

What would be the number of nodes extrapolating 500 devices sending within one minute, according to fair air usage ? I think it would be far from the theoretical 8k-20k nodes supported by a single...

Chris, The plan is indeed to start with a common sub-band for North America. This will maximise coverage initially, and get the project off the ground. We do the same in EU with a single channel plan....

Single Channel (Low Cost) Gateway
nmap: @Thomas: If we standardized default join channels and DR by region, then a deployment could get off the ground inexpensively using single-channel gateways. They would implement the LoRaWAN spec...

Thanks for posting this here, and adding your own thoughts and simulation! You need to be very careful in comparing these two technologies. For example, at a first glance it seems that the full...
